* docs: about: what-is-fluent-bit: mention profiles, OTLP, and fix vale suggestions - Update opening paragraph to explicitly list the telemetry signal types Fluent Bit processes (logs, metrics, traces, and profiles), aligning with concepts/key-concepts.md and fluentbit.io messaging. - Call out native OpenTelemetry (OTLP) ingestion and delivery rather than grouping it with general ecosystem integrations. - Split long sentences to improve readability. - Use "open source" instead of "open-source". Applies to #2539 Signed-off-by: Eric D. Schabell <eric@schabell.org> * docs: SUMMARY: rename entry to "What's Fluent Bit?" Applies to #2539 Signed-off-by: Eric D. Schabell <eric@schabell.org> * docs: about: fluentd-and-fluent-bit: add OpenTelemetry row to comparison table - Highlight native OTLP ingestion and delivery in Fluent Bit as a differentiator versus Fluentd's plugin-based OpenTelemetry support.

-[Fluent Bit](https://fluentbit.io) is an open source telemetry agent specifically designed to efficiently handle the challenges of collecting and processing telemetry data across a wide range of environments, from constrained systems to complex cloud infrastructures. Managing telemetry data from various sources and formats can be a constant challenge, particularly when performance is a critical factor.
+[Fluent Bit](https://fluentbit.io) is an open source telemetry agent that processes logs, metrics, traces, and profiles. It's designed to efficiently handle the challenges of collecting and processing telemetry data across a wide range of environments, from constrained systems to complex cloud infrastructures. Managing telemetry data from various sources and formats can be a constant challenge, particularly when performance is a critical factor.
 
-Rather than serving as a drop-in replacement, Fluent Bit enhances the observability strategy for your infrastructure by adapting and optimizing your existing logging layer, and adding metrics and traces processing. Fluent Bit supports a vendor-neutral approach, seamlessly integrating with other ecosystems such as Prometheus and OpenTelemetry. Trusted by major cloud providers, banks, and companies in need of a ready-to-use telemetry agent solution, Fluent Bit effectively manages diverse data sources and formats while maintaining optimal performance and keeping resource consumption low.

 Fluent Bit can be deployed as an edge agent for localized telemetry data handling or utilized as a central aggregator/collector for managing telemetry data across multiple sources and environments.

 ## The history of Fluent Bit
 
-In 2014, the [Fluentd](https://www.fluentd.org/) team at [Treasure Data](https://www.treasuredata.com/) was forecasting the need for a lightweight log processor for constraint environments like embedded Linux and gateways. To meet this need, Eduardo Silva created Fluent Bit, a new open-source solution and part of the Fluentd ecosystem.

To meet this need, Eduardo Silva created Fluent Bit, a new open source solution and part of the Fluentd ecosystem.
 
 After the project matured, it gained traction for normal Linux systems. With the new containerized world, the cloud native community asked to extend the project scope to support more sources, filters, and destinations. Not long after, Fluent Bit became one of the preferred solutions to solve the logging challenges in cloud environments.
